Definitions

  • the present invention relates to a modular system, and more particularly to a modular connector system, such as a modular rink system that can be assembled from modular components for seasonal use.
  • Backyard ice rinks have been traditionally fraught with challenges associated with the time, expense and know-how to construct these complicated, large scale projects, uneven lawn grades requiring high water/ice lines in low spots and therefore greater pressure and limited board space above the ice line in those areas, uncooperative weather conditions, and holes and rips in plastic liners putting an early end to the season. It's a daunting, trial and error process that can frustrate even the most diehard do-it-yourselfer.

  • the present invention relates to a modular connector system, such as a modular board connecting and stacking system, for facilitating the construction of a playing area or non-playing area, such as an outdoor or backyard ice hockey or skating rink, sand box, garden, fully enclosed, partially enclosed, walled-in, netted, partitioned area, and the like.
  • the modular system includes modular components which can be connected, for example, to form a rink.
  • the modular components include free-standing corner connectors and free-standing side connectors. Spanning boards can be used to join the side connectors to the corner connectors and other side connectors.
  • the corner connector includes a base having a stabilizing footprint which enables the corner connector to rest securely on the ground.
  • the base can take any shape capable of resting securely on the ground, such as for example, a triangle, square, trapezoid, rectangle, or the like.

  • the corner connector base is formed of three side members joined together end to end in the form of a triangle.
  • Each side member can have four ends.
  • the hypotenuse side member can be planar or curved.
  • the side member can have two rectangular surfaces, each surface connected by four ends.
  • the triangle base is preferably positioned such that one exposed side end of each side member is in contact with the ground.
  • the connector base components can take any form, such as planks, boards, injection molding, welded frame, and the like and be made from any combination of suitable materials, such as, wood, plastic, metal, composites, rubber, and the like.
  • the base is provided with a cut-out portion such as a void or cavity, which functions as a handle to facilitate ease of handling.
  • the corner connector is configured to receive the end of a horizontally positioned spanning board or set of horizontally positioned vertically stacked spanning boards via top installation in respective frictional slots on each of two side members positioned at approximately right angles to one another.
  • the corner connector can be any shape preferably having two sides at approximately right angles to each other with a frictional slot on each side.
  • the corner connector can be sized to accommodate a plurality of horizontally positioned vertically stacked spanning boards as desired.
  • Each frictional slot is bordered on three vertical sides (two side and one back) and open on the top, bottom, and remaining fourth vertical side (front).
  • the back side acts as a vertical “stop” for incoming spanning boards.
  • the frictional slots can be formed by a mounting/stop member or members attached to the surface of each of two side members positioned at approximately right angles to each other, and a clamping member attached to each mounting/stop member(s).
  • the thickness of the mounting/stop member(s) is approximately the same thickness of the spanning board and having sufficient clearance for the spanning board to be placed in the slot from the top.
  • the mounting/stop and/or clamping members are detachably fastened to each side member, for example by bolts, screws and the like, in a manner to clamp the spanning board in the frictional slot.
  • the mounting/stop and clamping members can be any suitable combination of form and material, such as planks, boards, metal tubes or plates, rubber or plastic.
  • the frictional slots or the backside stop/mounting member(s) can be formed by being built right into each of two side members positioned at approximately right angles to one another, through injection molding, welded, formed, or other manners.
  • the frictional slots can be formed by a single member, such as a molded piece of plastic, or formed or extruded metal, detachably clamped to each of two side members positioned at approximately right angles to one another, by bolts or other manners which can be tightened after the spanning board or set of spanning boards have been inserted into the frictional slot.
  • the corner connector allows the horizontally positioned spanning board or boards to stand firmly upright and evenly, vertically stacked once inserted in the frictional slots.
  • the side connector includes a base having a stabilizing footprint which enables the side connector to rest securely on the ground.
  • the base can take any shape capable of resting securely on the ground, such as for example, a triangle, square, trapezoid, rectangle, or the like.
  • the connector base can be formed using multiple pieces (or members) or could be a single piece formed from a mold. For purposes of the ensuing discussion, “side member” could be used interchangeably with “side”.
  • the side connector base is formed of three side members joined together end to end in the form of a triangle.
  • Each side member can have four ends.
  • the side member can have two rectangular surfaces, each surface connected by four ends.
  • the triangle base is preferably positioned such that one exposed side end of each side member is in contact with the ground.
  • the connector components can take any form, such as planks, boards, injection molding, welded frame, and the like and be made from any suitable material, such as, wood, plastic, metal, composites, rubber, and the like.
  • the base is provided with a cut-out portion such as a void or cavity, which functions as a handle to facilitate ease of handling.
  • the side connector is configured to receive the end of a horizontally positioned spanning board or set of horizontally positioned vertically stacked spanning boards via top installation in respective frictional slots positioned on the same side member along a substantially linear path to one another.
  • the side connector can be any shape preferably having one side which includes respective frictional slots positioned along a substantially linear path to one another.
  • the side connector can be sized to accommodate a plurality of horizontally positioned vertically stacked spanning boards as desired.
  • Each frictional slot is bordered on three vertical sides (two side and one back) and open on the top, bottom, and remaining fourth vertical side (front).
  • the back side acts as a vertical “stop” for incoming spanning boards.
  • the frictional slots can be formed by a mounting/stop member or members attached to the surface of a side member and a clamping member attached to the mounting/stop member(s).
  • the frictional slots are preferably positioned on the side member in the hypotenuse orientation.
  • the thickness of the mounting/stop member(s) is approximately the same thickness of the spanning board and having sufficient clearance for the spanning board to be placed in the slot from the top.
  • the mounting/stop and/or clamping members are detachably fastened to the side member, for example by bolts, screws and the like, in a manner to clamp the spanning board in the frictional slot.
  • the mounting/stop and clamping members can be any suitable combination of form and material, such as planks, boards, metal tubes or plates, rubber or plastic.
  • the frictional slots or the backside stops/mounting member(s) can be formed by being built right into a side member (in triangle form, the hypotenuse side) through injection molding, welded, formed, or other manners.
  • the frictional slots can be formed by a single member, such as a molded piece of plastic, formed, welded or extruded metal, detachably clamped to a side member (in triangle form, the hypotenuse side) by bolts or other manners which can be tightened after the spanning boards have been inserted into the frictional slots.
  • the side connector allows the horizontally positioned spanning board or boards to stand firmly upright and evenly, vertically stacked once inserted in the frictional slots.
  • the stabilizing footprint of the corner connector and side connector enables the connectors and spanning boards to be installed free-standing and without the need for ground securing stakes and the like. This feature facilitates easy installation of the playing area even when the ground is frozen. Furthermore, layout spacing may be easily adjusted to any length of spanning board since the connectors can be moved around and placed as needed during assembly.
  • the stabilizing footprint base is designed to facilitate efficient storage and handling when not in use. Since additional connecting hardware is not needed, assembly times are quicker than with prior art systems and uneven areas of the ground are readily accommodated by the free-standing nature of the stabilizing footprint base.
  • the modular rink system can be constructed from a plurality of corner connectors, side connectors, and spanning boards in a number of desired configurations.
  • a first corner connector is attached to a first side connector by a set of vertically stacked spanning boards and the first side connector is attached to a second corner connector by another set of vertically stacked spanning boards.
  • a third corner connector is attached to a second side connector by a set of vertically stacked spanning boards and the second side connector is attached to a fourth corner connector by a set of vertically stacked spanning boards.
  • the first corner connector is joined to the third corner connector through a desired number of similar spanning board-side connector-spanning board segments.
  • the second corner connector is joined to the fourth corner connector through the same number of spanning board-side connector-spanning board segments that joins the first and third corner connectors.
  • Spanning board lumber is commercially available in standard sizes of 2′′ ⁇ 12′′ and 2′′ ⁇ 10′′ in various lengths ranging from 8′ to 16′, and so on.
  • the frictional slot could also be sized to accommodate plywood and other suitable materials.
  • the space between the “stop” side of the frictional slot and the nearest corner of the connector base side receiving incoming spanning boards will contribute length to wall segments. For example, a 1 foot space between the “stop” sides of frictional slots on a side connector bracket will contribute 1 foot to the length of the wall segment.
  • a set of horizontally positioned vertically stacked spanning boards can measure to a height of at least two feet above the ground. Such a height accounts for variations in ground slope to provide sufficient side board surfaces above the water/ice line.
  • the spanning boards can be made from any suitable material, such as, wood, plastic, metal, composites, rubber, and the like.
  • the modular system may be turned into an ice rink by covering the playing area with a water barrier, such as a large plastic sheet.
  • the water barrier can be placed on the ground and extended to the base of the side walls, up along the walls and over the top of the walls.
  • the water barrier can be secured to the side walls, preferably with clips, staples, tape, and the like.
  • the water barrier can be secured to the side walls by a plurality of surface boards placed around the rink.
  • the surface boards are placed in slight overlapping end to end fashion around the rink.
  • the surface board is preferably a rectangular plastic board or other suitable material equipped with several brackets having an L-shape extending from the surface of the board and positioned adjacent an upper end thereof.
  • the opening of the bracket is the approximate size of the thickness of the side wall, which allows the surface board to be easily placed on and firmly rest on top of the side walls and hang over the interior of the side walls.
  • the water barrier is held in place sandwiched between the side wall and the surface board.
  • the surface board protects the water barrier from rips, holes, or tears via skates, pucks, and shovels and provides an interior wall playing surface. No attachment with screws, nails, or the like is necessary.
  • the surface board is flexible enough to curve around the corner connector and attach to the spanning boards on either side of the corner connector while providing a smooth angled or curved face so as to round the playing side of the corner.
  • the playing area surface is then filled until covered with water and allowed to freeze.
  • the surface board extends below the water line prior to freezing.
  • the elements of the side and corner connectors are the same as noted above, however a guide is added for stake insertion to the outside of each corner clamp or frictional slot and there is also a guide in the two front corners of each connector (corner and side connectors) through which stakes can also be inserted.
  • the corner clamps have added 4 screw holes so that top and bottom spanning boards can be secured to corner connectors (and each other). Adding this function prevents any backward slippage or tilting upward of the corner connectors (especially those under the greatest water/ice pressure). Also, these screws connect the spanning boards to each other which provides more weight to combat movement from pressure and in conjunction with the spanning board brace (explained below) helps align the edges of boards and prevent warping.
  • stakes could be inserted through guide on each corner clamp or frictional slot at a minimum, which will prevent outward movement of spanning boards due to pressure.
  • stakes could be inserted through guides in the two front corners only.
  • the guides could be formed using separate members, or could be incorporated/built into the connector base via injection mold or designed voids.
  • the guides could be of any suitable material such as molded plastic, formed or extruded metal, and the like.
  • the spanning board brace is a flat, one piece unit designed to be secured to and span across the height of the outside surface of a horizontally positioned spanning board or set of horizontally positioned vertically stacked spanning boards, in the middle of each spanning section (between connectors).
  • the spanning board brace is attached, for example by screws, to top and bottom spanning boards, and includes a guide for stake insertion, which will prevent outward movement of spanning boards due to pressure.
  • the spanning board brace could be formed from any suitable material such as molded plastic, formed or extruded metal, and the like.
  • Stakes for corner connectors, side connectors and spanning board braces are ideally of strong formed or extruded metal, such as angles or tubes, but could be of another material of suitable strength.
  • the light/net pole bracket holder (note hole in top and bottom of front crossbars in FIG. 6 ) can be used for other sports (net for baseball, etc.) as well.
  • the hole(s) for the light/net pole could be formed using separate members as illustrated, or could be incorporated/built into the connector base via injection mold or designed voids.
